Thank you Bowie-Won Kenobi, you're my only hope. Don't worry, everyone. My resolve is pretty strong. But I appreciate the enthusiasm!
Save for the tank itself and the lights, I have everything else: skimmer, pump, heater, controller, vortech. So I see myself sinking about $500 in equipment which is reasonable for me right now. I going to do a big fire sale of stuff I've collected over the years so hopefully I can break even.
If I prove to myself that I can keep this 40B, then a couple of years down the line, the 180 will be reborn. Yes, it will be. In the meantime, swim mbuna, swim!
